Airworthiness Directives; SOCATA Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for SOCATA 
Model TBM 700 airplanes. This AD results from mandatory continuing 
airworthiness information (MCAI) issued by an aviation authority of 
another country to identify and correct an unsafe condition on an 
aviation product. The MCAI describes the unsafe condition as landing 
gear actuator rod and piston becoming unscrewed during operation and 
the landing gear actuator ball joint becoming uncrimped. We are issuing 
this AD to require actions to address the unsafe condition on these 
products.

DATES: This AD is effective May 2, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of May 2, 2014.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to add an AD that would apply to SOCATA Model TBM 700 
airplanes. That NPRM was published in the Federal Register on December 
4, 2013 (78 FR 72834). That NPRM proposed to correct an unsafe 
condition for the specified products and was based on mandatory 
continuing airworthiness information (MCAI) originated by an aviation 
authority of another country. The MCAI states:

    During maintenance check, possible unscrewing of rod and piston 
during operation was detected on a landing gear actuator. 
Investigation showed that this was likely caused by maintenance 
operation not conforming with the procedure described in the SOCATA 
maintenance manual.
    Moreover, following in-service landing gear collapse, uncrimping 
of a right hand main landing gear (MLG) actuator ball joint was 
detected. Investigation revealed a manufacturing non-conformity of 
some actuator rod end assemblies.
    These conditions, if not detected and corrected, could lead to 
MLG or nose landing gear (NLG) failure during landing or roll-out 
and consequent damage to the aeroplane and injury to occupants.
    To address this potential unsafe condition, SOCATA issued 
Service Bulletin (SB) 70-197-32 to require a one-time inspection of 
the landing gear actuator piston/rod and SB 70-206-32 to require a 
one-time inspection of the landing gear actuator ball joint 
centering and, depending on findings, accomplishment of corrective 
actions.
    SOCATA also developed modification 70-0334-32, embodied in 
production to secure rod/piston assembly through addition of a pin 
and to reduce retraction/extension indication failure through 
improvement of switch kinematics. These modified actuators have a 
new part number (P/N).
    For the reasons described above, this AD requires a one-time 
inspection of the landing gear actuators piston/rod and ball joint 
centering and, depending on findings, accomplishment of applicable 
corrective actions.

    The MCAI can be found in the AD docket on the Internet at: http://www.regulations.gov/#!documentDetail;D=FAA-2013-1019-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment

[[Page 17394]]

received on the proposal and the FAA's response to the comment.

Reference Correction Within the Actions and Compliance Section

    Catherine Herau of DAHER-SOCATA requested we change the service 
information references in paragraph (f) of this AD in the Actions and 
Compliance section to clarify the AD.
    We agree with the commenter and changed our final rule AD action to 
reference the Accomplishment Instructions section of the service 
information rather than the specific paragraph.

Costs of Compliance

    We estimate that this AD will affect 495 products of U.S. registry. 
We also estimate that it would take about 2 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour.
    Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $84,150, or $170 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 3 work-hours for each main landing gear and 3 work-hours for 
the nose landing gear, and require parts costing $100 for each rod and 
assembly. We have no way of determining the number of products that may 
need these actions.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this AD will not have federalism implications 
under Executive Order 13132. This AD will not have a substantial direct 
effect on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government.
    For the reasons discussed above, I certify this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

Gear.

(e) Reason

    This AD was prompted by mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country to identify and correct an unsafe condition on an aviation 
product. The MCAI describes the unsafe condition as the landing gear 
actuator rod and piston becoming unscrewed during operation and the 
landing gear actuator ball joint becoming uncrimped. We are issuing 
this AD to detect and correct discrepancies in the pistons/rods and 
the ball joint centering of the nose landing gear and main landing 
gear, which could result in landing gear failure and lead to damage 
of the airplane and occupant injury.

(f) Actions and Compliance

    Unless already done, do the actions in paragraphs (f)(1) through 
(f)(4) of this AD on any airplane with the landing gear actuators 
part number (P/N) T700A3230050000, P/N T700A323005000000, or P/N 
T700A323005300000 installed:
    (1) Within the next 8 months after May 2, 2014 (the effective 
date of this AD), perform a detailed visual inspection (DVI) of the 
pistons and rods of the nose landing gear (NLG) and left hand (LH) 
and right hand (RH) main landing gear (MLG) actuators and measure 
the distance following the Accomplishment Instructions in DAHER-
SOCATA Mandatory Service Bulletin SB 70-197, dated April 2013.
    (2) Within the next 8 months after May 2, 2014 (the effective 
date of this AD), perform a DVI of the ball joint centering of the 
NLG and LH and RH MLG actuators and measure the ball joint mismatch 
following the Accomplishment Instructions in DAHER-SOCATA Mandatory 
Service Bulletin SB 70-206, dated April 2013.
    (3) If any discrepancy is found during any inspection required 
in paragraphs (f)(1) or (f)(2) of this AD, before further flight, 
replace the affected actuator or rod end assembly if applicable with 
an airworthy part following the applicable Accomplishment 
Instructions in DAHER-SOCATA Mandatory Service Bulletin SB 70-197, 
dated April 2013; and/or DAHER-SOCATA Mandatory Service Bulletin SB 
70-206, dated April 2013.
    (4) As of May 2, 2014 (the effective date of this AD), do not 
install on any airplane a landing gear actuator P/N T700A3230050000, 
P/N T700A323005000000, or P/N T700A323005300000, unless it is found 
to be in compliance with the inspection requirements of paragraphs 
(f)(1) and (f)(2) of this AD. The landing gear actuator must be 
installed when doing these inspections.
